Rifle choices are narrowed down to (to be used with a brand new Hill pump):
1) Daystate Huntsman XL with Permanently Bonded Airstream Reflex Mod (seems like the best choice)
2) Daystate Air Ranger (I would have to buy used as the new price is a bit higher than I'd like. I do like the flexibility of a non-permanently affixed silencer.)
3) Air Arms S510 (I don't like the adjustable power as it seems the wheel would need to be checked prior to each shot while hunting in brush or cover. This is also why I don't use target turrets on my hunting scopes. I have heard this brand and rifle are highly regarded, powerful, and very quiet.)

That's a good question. For my backyard pest removal and hunting trips, all 3 get plenty of full power shots with fairly quick follow up capability (rotating pellet magazines). The AA S510 does have a power adjustment valve but one can't lock it so the power regulation feature is more of a "con" for me.
